<p>A drawing is made of a pattern which it is desired to form into an impression in a clay or ceramic article, e.g. a brick or tile. A relatively thick printing plate has the pattern formed in its surface, by etching or laser cutting, to a depth of 1 mm to 5mm. The plate is then itself used as a wall portion of a mould in which the clay or ceramic material is pressed. The resultant pressed body is then removed from the mould and fired. A very high degree of detail can be formed on the clay or ceramic article in this way.</p> |
